B. B. BOLLINGER, OF LOUISVILLE, OHIO.

IMPROVEMENT IN REGISTERS FOR KNlTTlNG-MACHINES.

Specification forming part of Letters Patent No. 81,870, dated September 8, 1868.

To all 'whom it may concern:

Be it known that I, B. B. BOLLINGER, of Louisville, in the county of Stark and State of Ohio, have invented a new and Improved Knitting-Machine Register; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specifica tion.

The nature of my invention relates to improvements in knitting-machine registers, whereby it is designed to provide a sure and simple means of giving notice to the operator when any change isrequired to be made in the size or shape ofthe article bein g knit, by increasin g or diminishing the number of stitches and it consists in providing a pattern-wheel, the periphery of which is provided with notches, corresponding in distance from each other, to agree with the changes required to be made in the knit fabric, and which is operated through the medium of gearing connected to a ratchet-wheel, which receives motion from a pawl connected to some intermittingly-movin g part of the knitting-machine, the periphery of the said notched wheel causing a bell-hammer to strike as each notch passes a given projection on the arm of the bell-hammer, different sizes and gures of pattern-wheels being provided for diierent kinds of work, as will be more fully described on reference to the accompanying drawings, wherein is represented a side elevation of my improved register.

A represents a metallic frame for supporting the operative parts of my improvement, which may be arranged in any proper shape, to be secured to machines of different construction, but which is, in this instance, designed to be-secured to the arch of the Lamb knittingmachine. B represents an operatingpawl, that may be attached to the latchopener of the said machine, and which communicates motion to the ratchet-wheel O, the axle of which carries a pinion, c', working into the wheel D. E represents the pattern-wheel, which is secured to the shaft of the wheel D. F represents a spring-hammer, provided with a projection, F', on the shank, which works on the periphery of the pattern-wheel E. G represents a bell.

The pattern-wheel E may be made with not-ches in its periphery to correspond with the pattern to be knit, as will be well understood, the distances between the notches being calculated, together with the number of teeth and revolutions of the ratchet-wheel, pinion, and driving-wheel D, so as to give the requisite number. of threads to each section of the article being knit, the blow of the hammer on the bell notifyin gthe operator when the change in the number of stitches should take place to change the shape of the fabric.

It will be readily understood that di'erent patterns of wheels may be used for different articles; or, for making articles of diierent sizes of the same kind, the gear-wheels may be changed so as to increase or diminish the number of yarns to the section; or, if it be preferred not to alter the gear-wheels, different pattern-wheels may be used for diierent sizes ofthe same kinds of fabric or for yarn of different numbers.

I claim as new and desire to secure by Letters Patentl. The knitting-machine register, composed of a patternwheel, E, a spring-hammer, F, and au alarm-bell, substantially as and for the purpose described.

2. In registers for knitting-machines, the combination of the alarm-bell, hammer, and mechanism for moving the pattern-wheel, substantially as herein described.
